With over twenty years’ experience in insurance law, Aaron acts for clients in relation to coverage of insured losses in diverse sectors including financial services, hospitality and retail, energy and construction, sports and entertainment. He is experienced in all commercial lines of business, including business interruption, directors and officers, professional liability, cyber, environmental risks, property and casualty. Aaron spent eight years practising in the Asia Pacific region and is particularly experienced at resolving international and cross-border claims, often via arbitration.
Aaron’s cases were selected by The Lawyer as the only insurance cases to feature in the publication’s annual Top 20 Cases list in both 2022 and 2023, and as a Top 10 Appeal in 2024. In June 2023 he was named by The Times as Lawyer of the Week in recognition of the successful verdict in London International Exhibition Centre v RSA & Ors [2023] EWHC 1481 (Comm).
Aaron trained and practised with City and US firms in London before relocating to Asia in 2011, where he spent two years in-house as regional head of litigation for a global insurer in Singapore. He then returned to private practice to lead a dedicated insurance practice at Southeast Asia’s leading law firm, with offices in seven countries across the region.
After returning to London in 2019, Aaron led the products and environmental risks practice at a leading insurance boutique, before joining Stewarts to launch the firm’s Policyholder Disputes practice in 2022.
